timer problem

[neverasunset]

my timer starts ok but after a few ticks it counts down a lot faster

here is my code:

$TIME = TimerInit()

    While 1
        $HOURS = (GUICtrlRead($INPUT_HOURS1)*10)+GUICtrlRead($INPUT_HOURS2)
        $MINUTES = (GUICtrlRead($INPUT_MINUTES1)*10)+GUICtrlRead($INPUT_MINUTES2)
        $SECS = (GUICtrlRead($INPUT_SECONDS1)*10)+GUICtrlRead($INPUT_SECONDS2)
        $TIME_NEW = TimerDiff ($TIME)
        $TIME_NEW = ((($HOURS*3600)+($MINUTES*60)+$SECS)*1000)-$TIME_NEW
        $SECONDS = Round($TIME_NEW/1000)
        $HOURS_REFRESH = Floor($SECONDS/3600)
        $MINUTES_REFRESH = Floor(Mod($SECONDS, 3600)/60)
        $SECONDS_REFRESH = Mod($SECONDS, 60)
        GUICtrlSetData($INPUT_HOURS1, Floor($HOURS_REFRESH/10))
        GUICtrlSetData($INPUT_HOURS2, Mod($HOURS_REFRESH, 10))
        GUICtrlSetData($INPUT_MINUTES1, Floor($MINUTES_REFRESH/10))
        GUICtrlSetData($INPUT_MINUTES2, Mod($MINUTES_REFRESH, 10))
        GUICtrlSetData($INPUT_SECONDS1, Floor($SECONDS_REFRESH/10))
        GUICtrlSetData($INPUT_SECONDS2, Mod($SECONDS_REFRESH, 10))
        Sleep(1000)
    WEnd

I think it's because of an error in your logic.

You have a start time $TIME

you calculate the time left lets say it's CURRENTTIME

You then see how much time has elapsed since $TIME and you take that from CURRENTTIME to give a new CURRENTTIME.

But you should take elapsed time from the very first reading of the set time, not the new current time.

Or, every time you calculate the elapsed time reset $TIME with TimerInit, but I don't think that will be so accurate.

thanks for pointing that out

ill give it another go with your input in mind
